Landscape unit
Definition
Landscape units are portions of the catchment with similar morphological characteristics.
Delineation criteria
The catchment is divided into landscape units that are broadly consistent in terms of their topography, geology and land cover, as these factors determine the hydrological responsiveness of a catchment and the source and delivery of sediment to the river system.
Methods and data sources
GIS overlay of some of the following in the stated order of priority
- Digital Elevation Model (e.g. EU-GDEM)
- Geological maps (One Geology Europe)
- CORINE Land Cover
- Supporting information from: Google Earth / Orthophotos
The Frome catchment was delineated into 3 landscape units based on elevation, geology and land cover.
